Engineering Selection Recommendations

All identified substitute parts are manufactured by TT Electronics/Optek Technology and maintain active product status, ensuring ongoing availability and supply chain continuity. Each substitute part carries ROHS3 compliance and REACH unaffected certification, meeting current regulatory requirements for electronic component procurement.

The OPB360N51 represents the direct variant of the obsolete OPB360N55, differing only in packaging designation (Bulk versus unspecified). This part provides the most direct replacement path while maintaining identical electrical and mechanical specifications.

The OPB365 series (OPB365N11, OPB365N51, OPB365P55) and OPB370 series (OPB370N51, OPB370N55) offer parametric equivalency across all critical specifications. The OPB370N55 demonstrates the highest inventory availability at 90,400 units, supporting procurement flexibility.

The OPB375N51 and OPB380 series (OPB380N11Z, OPB380P51Z, OPB380P55Z) complete the substitute portfolio, each maintaining full parametric alignment with the original OPB360N55 specification.

Frequently Asked Questions (FAQ)

Q: Can OPB360N51 directly replace OPB360N55 in existing designs?

A: Yes. The OPB360N51 maintains identical electrical specifications (50 mA forward current, 30 mA collector current, 30 V breakdown voltage), operating temperature range (-40°C ~ 85°C), sensing distance (0.125"), sensing method (through-beam), output configuration (phototransistor), and mounting type (chassis mount, pre-wired module). The only difference is packaging designation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance and REACH unaffected certification, meeting current regulatory standards for electronic component procurement and use.

Q: What distinguishes the OPB365, OPB370, OPB375, and OPB380 series from the OPB360?

A: These represent different base product numbers within the TT Electronics/Optek Technology optical sensor portfolio. All maintain identical electrical and mechanical parameters specified for the OPB360N55, including sensing distance, output configuration, current ratings, voltage ratings, operating temperature, and mounting type. Substitution is valid across all series based on parametric equivalency.

Q: Does packaging type (Bulk) affect electrical performance?

A: No. Packaging designation indicates distribution format only and does not alter electrical specifications, performance characteristics, or functional compatibility. All substitute parts maintain identical electrical and mechanical parameters regardless of packaging type.

Q: Which substitute part offers the best procurement availability?

A: The OPB370N55 demonstrates the highest inventory availability at 90,400 units in stock, providing optimal supply chain flexibility for procurement planning.

Q: Are there any temperature or environmental limitations that differ between the OPB360N55 and its substitutes?

A: No. All substitute parts maintain the identical operating temperature range of -40°C ~ 85°C and moisture sensitivity level of 1 (Unlimited), ensuring equivalent performance across all environmental conditions.
